Endora casts a spell on Darrin which causes him to vanish whenever he speaks Spanish. Trouble is, Darrin has been shipped off to Mexico City, where he has been hired to promote a product called "Bueno." Thomas Gomez guest stars as Darrin's client, Mr. Garcia. Written by John L. Greene, "Samantha and Darrin in Mexico City" originally aired on April 24, 1969, as the final episode of Bewitched's fifth season -- and the last episode to feature Dick York as Darrin Stephens. ~ Hal Erickson, Rovi
